What brand is the engine of the GAC Trumpchi GS4?

[MatthewDella]

4A15J1 is the engine model used in the GAC Trumpchi GS4, with a maximum horsepower of 169 HP, a maximum power of 124 KW, a maximum power speed of 5000 rpm, and a peak torque of 265 N·m. The engine of the GAC Trumpchi GS4 is a 1.5T engine, produced at the GAC Trumpchi Panyu Powertrain Factory. For the daily maintenance of the GAC Trumpchi GS4 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to the mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, causing various problems for the engine. To avoid malfunctions, the oil should be changed regularly based on usage conditions, and the oil level should be kept moderate. When the oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and the oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing the oil to bypass through the bypass valve and bring contaminants back to the lubrication area, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder generated by component wear to form sludge. When the amount is small, it remains suspended in the oil; when the amount is large, it precipitates from the oil, clogging the filter and oil holes, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and the engine.

I've driven several models of the Trumpchi GS4, and their engines are basically the third-generation 270T series independently developed by GAC, which is a 1.5T turbocharged engine. The engine technology is quite interesting, featuring GCCS combustion control patents, a low-inertia turbocharger, and high-pressure direct injection. In daily driving, the power response is quick, and fuel consumption is decent, averaging around 8L for city commuting. I noticed that the new models also come with a 48V mild hybrid system, making low-speed driving quieter. Domestic brands have indeed made significant progress in recent years, and the reliability of Trumpchi engines is good—I know car owners who have driven for five or six years without major repairs. If you consider long-term maintenance, the price of parts at 4S stores is about 30% cheaper than joint-venture brands, making it a relatively worry-free choice.

The GAC Trumpchi GS4 is powered by a 1.5T engine independently developed by GAC, codenamed 270T, which belongs to the third generation. It delivers a maximum power of 124kW and torque of 265 N·m, paired with an Aisin transmission for smooth power delivery. Compared to its peers, this SUV boasts a leading thermal efficiency in its class, primarily due to the adoption of dual continuous variable valve timing technology. In real-world driving, the turbo kicks in promptly during acceleration, and highway overtaking feels stable, though the engine noise becomes slightly noticeable during hard acceleration. For routine maintenance, 5W-30 oil is sufficient, and the air filter should be replaced every 10,000 kilometers, making it cost-effective to maintain. For used models, particularly those manufactured before 2015, it's important to check for cylinder carbon buildup as they might be equipped with Mitsubishi's 4B series engines.

As a repair technician, I've handled hundreds of GS4 vehicles, most equipped with GAC's self-developed 270T engine. This 1.5T engine features an all-aluminum cylinder block for lightweight and excellent heat dissipation, with direct injection pressure reaching 200bar for high combustion efficiency. Common issues include coolant leaks or turbo pressure sensor failures, but core component failure rates are lower than older Mitsubishi models. I recommend changing the oil at 5,000km for new vehicles - semi-synthetic oil is sufficient. For DIY maintenance, remember to use a 16mm socket when removing spark plugs. Note: Pre-2018 models occasionally experience camshaft phaser noise, usually caused by dirty oil - timely maintenance can prevent this.
